Slip-proof shoelace

ABSTRACT

A slip-proof shoelace being characterized in that: a slip-proof member with a larger coefficient of friction (such as made of silicone, rubber or chemical plastic weaving fiber) is provided on a suitable length extending from each of two ends toward the other end of the shoelace. The slip-proof member can be an elastic sleeve with a smooth surface or a plurality of annular ribs, helical ribs or granules, extending from an end toward the other end of the shoelace, so that the shoelace forms an engaging action at the tying up area, and by the feature of having a larger coefficient of friction, the shoelace can be prevented from loosening and dropping.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a member for tying up a shoe.

2. Description of the Prior Art

Conventional shoelaces for tying up shoes generally are made of cotton,nylon, chemical plastic weaving fiber etc., the two ends of a shoelaceare combined each with a leading portion which is harder anddiametrically smaller than the main body of the shoelace. By guiding ofthe leading portions both with smaller diameters, the shoelace can beconveniently extended through shoelace holes on the shoe, and then theshoelace can be tied up on the shoe.

In wearing shoes, people often feel that shoelaces are subjected toloosening. To look into the reason of this, it is found that this isbecause that the coefficient of friction of the shoelaces is lower,especially on those shoelaces having smooth circular or flat sectionsand made of plastic, the shoelaces thereby are more subjected toloosening once they are not tightly tied up. However if the shoelacesare overly tied up, those wearing the shoes will feel uncomfortable.

SUMMARY OF THE INVENTION

The main objective of the present invention is to solve the defect thatconventional shoelaces are subjected to loosening during exercising.

In view of this, the primary technical measure of the present inventionis to provide a slip-proof member with a larger coefficient of friction(such as made of silicone, rubber or plastic on a suitable lengthextending from each of two ends toward the other end of a shoelace, inorder that when the shoelaces are tied up, the shoelaces can beprevented from loosening by providing the member which has relievedparts and has a large coefficient of friction.

The slip-proof member of the present invention can be designed accordingto the idea of the designer to be an elastic sleeve with a smoothsurface or a plurality of annular ribs, helical ribs or granules,extending from an end toward the other end of a shoelace, so that theshoelace has a function of slip proofing after being tied up to a shoe.

In comparison with a conventional shoelaces, in addition to having thefeatures of easiness for threading and tying up as of the conventionalshoelace, the present invention further has the effect of looseningproofing, so that the present invention is practicable and improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring firstly to FIG. 1, a preferred embodiment of the presentinvention is to make the main body of a shoelace 1 using any suitablematerial, e.g., using normally used cotton, nylon or chemical plasticweaving fiber; and the main body of the shoelace 1 is provided with aslip-proof member 2 with larger a coefficient of friction on a suitablelength extending from the end rearwards of the shoelace 1, theslip-proof member 2 can be made of silicone, rubber or chemical plasticweaving fiber etc. with a larger coefficient of friction.

The slip-proof member 2 provided on the shoelace of the presentinvention can have multiple embodiments of practicing structurally,among them the first embodiment of the slip-proof member 2 is shown inFIG. 1, the main body of the shoelace 1 is provided with a plurality ofannular ribs 21 extending from an end toward the other end of theshoelace 1 for a suitable length (as shown in FIG. 1). The end of theshoelace 1 still is provided with a leading portion 11 as is the case ofa conventional shoelace for the convenience of threading through aplurality of holes (as shown in FIG. 2). With the structure of shoelace,after being tied up of the shoelace 1, the slip-proof member 2 having alarger diameter than the main body of the shoelace 1 forms an engagingaction at the tying up area, and by the feature of having a largercoefficient of friction, the shoelace 1 after tying up is not subjectedto loosening and dropping.

FIG. 3 shows the second embodiment of shoelace of the present invention,two slip-proof members 2 provided on the two ends of the shoelace 1 areelastic sleeves 22 with smooth surfaces, the elastic sleeves 22 arebound on the ends of the shoelace 1 by elastic binding force. Similarly,the ends of the shoelace 1 also are still provided each with a leadingportion 11 for the convenience of threading through a plurality ofholes. After being tied up of the shoelace, the slip-proof member 2having a larger diameter than the main body of the shoelace 1 forms anengaging action at the tying up area too, and by the feature of having alarger coefficient of friction, the shoelace 1 after tying up is notsubjected to loosening and dropping.

FIG. 4 shows the third embodiment of shoelace of the present invention,the main body of a shoelace 1 is provided with a plurality of helicalribs 23 extending from an end toward the other end of the shoelace 1 fora suitable length, and the ends of the shoelace 1 also are stillprovided each with a leading portion 11 for the convenience of threadingthrough a plurality of holes.

FIG. 5 shows the fourth embodiment of shoelace of the present invention,the main body of a shoelace 1 is provided with a plurality of granules24 extending from an end toward the other end of the shoelace 1 for asuitable length, and the ends of the shoelace 1 also are still providedeach with a leading portion 11 for the convenience of threading througha plurality of holes.

The embodiments as above mentioned are only for illustrating the presentinvention, it will be apparent to those skilled in this art that variousequivalent modifications or changes according to the idea of and withoutdeparting from the spirit of this invention shall also fall within thescope of the appended claims.
